l. In a contilnious acting centrifugal nia chine, a sieve arrailged. at an angle relative to the path of centrifugal. action of the inachine and operated by the .centrifuged inaterial.`

2. In a continumis acting centrifugal nia chine, a sieve arranged atan: angle to the path of niotion of, the centrifug l material and adapted for longitlildinal movement by and for rotation with the centrifiurfetl inaterial.

In a coi'itinuous acting centrifugal nia chine, a series of Je1l:' nated vertical. partitions arranged to ri-wolve about the axis of the machine and (.foiniected together to forni bands, and guiding means for said bands, said lfiartiti'ons being :ilrra'nged at` an angle relative to the path of centrifugal action of tlie-niachine for movement-hy and with the centrifuged inaterial.

In a continuous acting mzntriilug-gal inachine, a series of perforated vertical partitionsv arranged. at an angle Irelative to the action of the i'l'iaohine for i'novement by and with the centrifuged. niaterial, each partition coiisisting of a. plurality of juxtaposed retaining hars arranged transversely of the plane of revolution of the machine.

5. In a contiim'ons acting centrifugal inachine, a series bflperforated vertical parti `tions arranged for n'iovernent by and with the centrifuged material, each Apartition con sisting f; f a pluiiality of retaining bars located c. e together ,and transversely of the plane 'of revolution of the `machine, said bars being connected to forni an endless band.

In` a. continuous acting centrifugal Inacliine, series of perforated Vertical parti tions arranged foi-'movement by and with the centrifuged material, each partition consisting of a. plurality of retaining bars located close together and transversely of the pl ane of revolution of the machine, endless chains to which said bars are con nccted, and toothed rollers over Whicli said chains run.

7. ln a continuous acting centrifugallnae chine, the combination of a series of vertical partitions lcomiected with each other to constitute an endless element arranged at an angle relative to the action of the machine and for movement by and -with the centrifuged material, a revolnble freine,` rollers borne by the frame, a chamber arranged Within said endless element andhaving a discharge orifice extending 'through said frame. and means for continuously feeding lmaterial to be centrifuged `to the face of said partitions.

8. In a continuous actingcentrifugal machine, the combination of one or more vertical perforatedv partitions connected with each other to constitute an endless element,

and arrangedfor movement by and With'the` centrifuged material, a revoluble frame,

rollers borne by the frame, and a chamberv Within said endless element and provided 4with a perforated front Wall, a discharge orifice extending through said frame, and a rear Wall sloping toward said orifice.

9. In a'continuous acting centrifugal ma.-4 chine, the combination of a revoluble frame, rollers journaled therein, an endless sifter movable around said rollers and arranged at an angle relative to the path of `centrifugal action of the nia-chine, and feeding means revoluble vwith said frame for continuously supplying material to be centrifugedV -to the face of said sitter facing the direction of motion of the saine, said sitter having outer projecting crossmembers and inner means for engaging said rollers.

10. vIn a continuous acting centrifugal machine, the combination of a revoluble frame; rollers journaled therein, an endless sifter movable around said rollers and arranged at an angle relative to the centrifugal actlon of the machinegfa'nd feeding means revolu-l ble with said frame for continuously supv plying material to be centrifuged to the face i of said sifter at an angle to the direction of motion of the same, said feedin means corn.-

prising a supply pipe having a ranch open- 1n through a lateral slit adjacent said si ter. y v

1l. In a continuous acting centrifugal machine, the combination, with al series 0flsieves arranged to travel at aun angle relative to the path of centrifugal action, of feeding means opening in a p ane coincident with the force of centrifugal action and at an angle. to the path of travel of said sieves, for

causing the operation of the sieves.v by the discharge of the material to be treated.
